A steep hill.
(sorry, couldn't help myself).
Seriously, the first things to look at to make a stock engine gain power is:
1. Air Intake.
If an engine can more easily consume air, or if air can be forced into the intake (ram air hood scoops, turbo, supercharger) that can boost power. Cold air intakes are affordable and easily installed. The stock air filter box is removed and a round duct is installed, heading from the intake manifold to the font corner of a fender (usually driver's side) just in front of the wheel well, where air that hasn't been heated up in the engine compartment can be drawn in. Colder, outside air is more dense and gives more power.
2. Exhaust.
Getting an aftermarket exhaust system can make a very mild-to-moderate boost in performance. To make the most difference, however, the stock exhaust manifolds would have to be replaced with less restrictive headers, and a hi-flow catalytic converter would have to be installed as well. The idea is to provide as little resistance to exhaust gasses as possible.
3. ECU modification.
Your car's computer is programmed for economy, with performance being a secondary priority. In some cars, 30 percent performance boost is theoretically possible by installing a performance chip upgrade. Results vary very much from model to model. Search for owner reviews, and see what customers are saying about a chip upgrade you are considering.
There really is a fourth, general statement regarding performance. Be sure your transmission fluid and engine oil are maintained and repaced when appropriate. Friction kills and slows down cars from the inside.
Make sure your tires are inflated properly and the spark plugs are fresh. Start with a healthy car before modifying.

That depends on how much money you want to spend. As the poster above wrote modifying air intake and exhaust (header pipes and / or cat-back system) will improve it somewhat. But that kind of mod will only make your car fast by only a little (I've done both). But it is still fun to do.
Then depending on your budget and car, you can go drastic and start engine mods. But I am not a fan of this route. Much of it depends on your engine builder and it is a real money pit.
One last thing people don't seem to know is that by swapping tires to lower profile (smaller diameter) you increase toque and HP. But people are into big wheels not smaller wheels.
Good Luck.

You can bore out the cylinders and use oversized pistons, use a mod chip, change the transmission, etc... All depends how much you want to spend really.

A better driver.
Whenever I have a better driver in my car it goes faster. When I have a worse driver it goes slower.

Improve the intake and exhaust. Get a mod chip for your engine's EFI controller.

depends on what model it is, what you do to it and how much your wallet can afford ;)
